Adjustment of Status - I-485

I received a call from USCIS this morning, the lady said my case just got assigned to her and she wanted to confirm my address because they were multiple on file and she needs to send me some documentation so she wanted to be sure where she was sending them to. she then asked me when I go back to work offshore (so that I do not miss the letters) which I told her not to worry since my husband will be home and he can always let me know about the letters. She then told me she will review my case and make a decision, she said she doesn't know if there is need for second interview but she will be sure to let me know after reviewing my case. I am really really nervous and keep checking my app for updates. I do need to submit a new medical so I am not expecting to get a "New card is being produced" anyways.

I also think my case is moving fast because I filed Mandamus.
